To reproduce:

1) Download and open project
2) Build and run for iOS
3) Compare the texts shown on a device and in the editor game view
4) Notice that the last two symbols don't match (After consulting with the client, he stated that in the editor, the text 为什么房令 is Chinese, whereas on the device, the last two symbols appear to be Japanese)

Note: In the Inspector I noticed the same problem. With the Main Camera selected in the testfont scene, see that in the GUIText component the text shown doesn't match the one that is seen in the game view. (For the Japanese symbols, see attached image)
